Mild Steel Laser Cutting & Engraving

Laser cutting can be used for a variety of metals, including mild steel. Starting with 150 watts to 400w, mild steel can be cut at varying thicknesses (up to .1875”) with a CO2 laser.

Usually using oxygen as an assist gas, cutting happens when the material is heated to its melting point, resulting in a clean edge and dross-free cut. Lasers create narrow kerf lines and achieve a highly accurate cut, resulting in minimal material waste.
